Image-guided placement of totally implanted vascular access device: retrospective analysis of the clinical outcomes and associated risk factors

OBJECTIVES

To determine risk factors for catheter survival and complications after image-guided implantation of a totally implanted vascular access device (TIVAD).

METHODS

A total of 2883 TIVADs (2735 patients, 63.5±13 years old, 1060 men, 1675 women) implanted under guidance by ultrasound and fluoroscopy in our institution from January 2010 to December 2019 were evaluated retrospectively. We used the log rank test and logistic regression to analyse risk factors associated with catheter survival and complications.

RESULTS

Female patients (n=1778; 61.7%; mean catheter survival days: 780.6 days) and those with a haematological malignancy (n=277; 10.1%; mean catheter survival days: 1019 days) had significantly better catheter survival than male patients (n=1105; 38.3%; mean catheter survival days: 645.9 days) and those with a solid organ malignancy (n=2447; 89.5%; mean catheter survival days: 701 days) (p<0.001 and p=0.003). Patients with haematological malignancies and benign vascular inflammatory disease (n=11; 0.4%) were vulnerable to infection (n=96; 3.3%) (p<0.001 and p=0.004). Thrombotic malfunction (n=38; 1.3%) was significantly more common in females than males (p=0.005). Non-thrombotic malfunction (n=16; 0.6%) showed a significant association with left positioning of the TIVAD (n=410; 14.2%) (p=0.043). Wound dehiscence (n=3; 0.1%) was significantly more frequent in punctured veins other (n=23; 0.8%) than the internal jugular vein (p<0.001).

CONCLUSIONS

Increased attention should be paid to patients with an underlying haematological malignancy, underlying vascular inflammatory disease, female patients, older patients, those accessed via a vein other than the IJV, those with left positioning of the TIVAD system or those with a prolonged TIVAD maintenance.

Risk factors for complications in cancer patients with totally implantable access ports: A retrospective study and review of the literature

OBJECTIVES

To analyze the risk factors for complications associated with the use of totally implantable access ports (TIAPs) in cancer patients.

METHODS

Data for 2,713 cancer patients who received a TIAP between January 2010 and September 2016 at a single center were analyzed retrospectively.

RESULTS

The average age of the patients was 54.2 ± 9.92 years, and 1,247 (47.5%) were women. The right subclavian vein was the preferred insertion site. Seventy-seven patients developed early complications and 50 developed late complications. The incidence of complications increased as the number of punctures increased. Percutaneous intervention increased the risk of complications during port insertion, but age, sex, body mass index, and the use of physiological saline solution instead of heparin for washing after port insertion did not increase the risk. The use of ultrasonography during insertion reduced the risk of complications.

CONCLUSIONS

Various factors may affect the function of TIAPs in cancer patients both during insertion and follow-up. Age, sex, body mass index, and the use of physiological saline solution for washing did not affect the incidence of complications, but the use of ultrasonography during insertion did affect the complication rate.

Hypnosis as adjunct therapy to conscious sedation for venous access device implantation in breast cancer: A pilot study

BACKGROUND

Recent reviews support that hypnosis has great potential for reducing pain and anxiety during mini-invasive surgery. Here, we assessed the feasibility of hypnotic induction session as adjunct therapy in conscious sedation for venous access device implantation. Primary outcomes were safety and patient satisfaction.

METHODS

Thirty consecutive women with breast cancer were proposed adjunct of hypnosis before implantation under conscious sedation (midazolam: 0.5 mg ± bolus of Ketamin: 5 mg on demand) indicated for chemotherapy. Self-hypnosis was programmed and guided by one of two trained anesthesiologists. Implantation was performed by one of two experimented surgeons. It consisted of blind subclavian implantation of Braun ST 305 devices using a percutaneous technique adapted from Selinger's procedure. Clinical data were prospectively collected and retrospectively analyzed. A comprehensive custom-made questionnaire recorded patient satisfaction.

RESULTS

In all, 30/30 patients consented to the procedure. The median age was 54 years (range: 35-77 years). The primary procedure was successful in 29/30. One case was converted into internal jugular vein access after a first attempt. Median length time of the implantation procedure in the operative room was 20 min (range: 10-60 min). Median length time in the recovery room preceding home discharge was 65 min (range: 15-185 min). None of the patients suffered complications. The satisfaction rate was ≥90%, 27/30 patients would get hypnosis in case of reimplantation if necessary and 27/30 would recommend this procedure to others.

CONCLUSION

Hypnosis under conscious sedation appears feasible and safe for port implantation under conscious sedation in cancer patients. Further studies would determine the exact value of hypnosis effectiveness.

Common and uncommon complications of totally implantable central venous ports: a pictorial essay

PURPOSE

The purpose of this study is to present the characteristic radiologic features of common and uncommon complications in totally implantable central venous ports.

MATERIAL AND METHODS

The authors reviewed 138 implantations of central venous ports in oncologic patients during an 18-month period and present the characteristic imaging features of the complications detected.

RESULTS

All chest ports were placed via the internal jugular vein using both fluoroscopic and ultrasound guidance. The technical success rate was 99.3% (137/138). All catheter or port-related complications were retrospectively assessed. Sixteen complications were detected during the follow-up period, and catheter removal was required in 10 patients.

CONCLUSIONS

Image-guided central venous port catheter implantation is a very safe procedure with a low rate of complications. The typical imaging features of common and uncommon complications are very helpful in establishing the correct diagnosis and thus tailoring the appropriate therapy.

Evaluation of Radiologically Implanted Central Venous Port Systems Explanted Due to Complications

Purpose

The aim of this study was to evaluate explantations of central venous port systems that were implanted by interventional radiologists in cases where complications demanded the removal of the port device.

Methods

In this retrospective single-center study, explantation rates of central venous port catheter systems (CVPS) associated with complications were investigated over a 10-year period. All CVPS were implanted and explanted in our radiology department's interventional suite. Port catheter dysfunctions were divided into early and late complications, as well as into nonthrombotic and thrombotic events. Indications for implantation and explantation as well as clinical demographics were considered.

Results

One hundred and ninety-three CVPS were removed from 182 patients, due to complications. The total indwelling time of all CVPS was 55,132 catheter-days (mean 285.7; range 1–2,704). The most common diagnoses were gastrointestinal cancers 77 (39.9%) and hematological malignancies 32 (16.6%). Bloodstream infections 134 (69.4%) were the most common indication for the explantation procedure. These were followed by catheter-related thrombosis 28 (14.5%), nonthrombotic CVPS dysfunction 18 (9.3%), port pocket infections 9 (4.7%), and others 4 (2.1%). The highest percentages of explantations related to bloodstream infections were observed in patients with malabsorption (81.8%) and hematological malignancies (81.3%).

Conclusion

Bloodstream infections were the most common cause for port explantation, followed by catheter-related thrombosis. Complication-related explantations were mainly for late-onset complications. Prevention and management strategies should be applied regarding care and usage of port systems to reduce the rate of complication-related explantations.
